As the current travels down the nerve pathway, the electrodes placed along the way capture the signal and time how fast the signal is traveling.

Then the doctor stimulates the nerve with an electric current. NCS are often done along with the EMG to determine if a nerve is functioning normally.The doctor conducting the test will tape wires (electrodes) to the skin in various places along the nerve pathway. EMG results can help the doctor diagnose muscle disorders, nerve disorders, and disorders affecting the connection between nerves and muscles. These symptoms may include tingling, numbness, or unexplained weakness in the limbs. A doctor will usually order an EMG when someone is showing symptoms of a muscle or nerve disorder. An EMG translates these signals into graphs or numbers, helping doctors to make a diagnosis. They transmit electrical signals that cause muscles to contract and relax. These nerve cells are known as motor neurons. If appropriate, our physical therapist will design a personalized treatment plan for your specific needs to help relieve your pain and correct your condition.Electromyography (EMG) is a diagnostic procedure that evaluates the health condition of muscles and the nerve cells that control them. Your physician will review your results with you at your next appointment. Our physical therapist can also provide you with remedies you can do at home to ease any discomfort.Īfter your EMG is complete, our physical therapist will analyze the EMG test and send the results to your physician. If you notice some soreness from the movement following the EMG, it should go away shortly. You may also be asked to change positions in the way you are sitting or lying down during the testing. You may notice some discomfort with movement, but our physical therapist will not ask you to make any extreme movements to the muscle. You may be asked to move the affected area in certain ways or contract the affected muscle, in order to determine which signals are being affected and where the areas of inactivity are present. There may be some pain as the needle is removed, but that should disappear shortly after. When the needle electrode is inserted into the affected muscle, you may feel some slight discomfort, but it should not be painful.
